Neutrino as a router

Hello, all

I’m trying to setup Neutrino as a router. I am using the full TCP/IP stack and have IP forwarding turned on via the command-line switch. However, computers can’t connect to computers on the opposite side of the router:


±+ ±+
|A|-----+ ±----|C|
±+ | ±+ | ±+
±----|R|-------+
±+ | ±+ | ±+
|B|-----+ ±----|D|
±+ ±+

A and B can talk to each other and to R (the router). C and D can talk to each other and R. R can talk to all 4.

Anybody have any idea how I can fix this? I need all computers to be able to talk to each other.

Cheers,
Kevin

Without IP addres/netmask/routing table (netstat -ni, netstat -nr),
this is just a guess.

On A and B run:

route add C R

route add D R

On C and D run:

route add A R

route add B R

Or

on A,B,C,D run:

route add default R

ipfilter/NAT package for RTP is available. Using NAT you can peacefully setup
